Joel 2:28-32

And it will be that, afterwards, I will pour out My Spirit on all flesh; then your sons and your daughters will prophesy, your old men will dream dreams, and your young men will see visions. Even on the menservants and maidservants in those days I will pour out My Spirit. Then I will work wonders in the heavens and the earth— blood and fire and columns of smoke. The sun will be turned to darkness, and the moon to blood, before the great and awe-inspiring day of the LORD comes. And it will be that everyone who calls on the name of the LORD will be saved. For on Mount Zion and in Jerusalem there will be deliverance, as the LORD has said, and among the survivors whom the LORD calls.
